AIR-BATH APPARATUS.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed December 15, 1904. Serial Ij'o. 237,045.

To all whom it may concern:

Be it known that I, FRANK S. BETZ, a citi' zen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Air-Bath Apparatus, of which the following is a specification.

My invention relates to a paratus for treatingldisease by the application of heated air to t e body.

The main objects of my invention are to provide an improved construction for the supporting frame and carriage in devices of this class.

I accomplish these objects by the device shown inthe accompanying drawings, n

-' with a plurahty of funnel shaped air inlets which: Figure 1 is a side elevation of a hot air invention,

Fig. 2 is an end elevation of the same. Fig.

,3 is a transverse section of the casing and the parts therein, said section being taken on the ne 3-3 of Fig. 1. Fig. 4 is a detail in lan showing the method of securing the trac to the su porting frame.

In the construction shown, the casing 4 is substantially cylindrical in form and is rigidly mounted in a horizontally disposed position in the supporting frame 5'. 5 consists of a plurality of uprights 6 each resting u on the floor, and rigidly connected together y jointed cross-bars 7 below the casing 4, and by cross-bars 8 extending throu h the casing 4. Horizontal tracks 9 exten longitudinally along the inner walls of the casing and are rigidly connectedto the cross-bars 8, preferablyin the manner shown in Figs. [5 and 4, whichpermits of quickly disconnecting the casing from the supporting frame by simpl removing the nuts 10, for the purpose 0 packin the device. The joint .11 in the middle 0 provided for a similar 'pur ose.

The casing 4 is provide with an o ening 12 at one end to permit the bod of t e pahe 0 enin' 12 is provided with, a flexib e hood adapted to fit snugly around the neck of the patient and prevent the escape of heat through the opening 12. This hood is not shown-'in'the drawings. The body of the patient is supbath apparatus constructed according to my, the casing being shown in section.

he frame the cross-bars 7 is ported by a horizontally disposed platform or litter 13 which is provided at its inner end with a pair of flanged rollers 14. adapted to ride on the tracks 9 and its outer end is secured to the u right su ports 15 which are mounted on ro ers 16 a apted to ride on the floor to permit the platform to be moved into and out of the casing. To provide additional support for the platform the tracks at the open end of the casing are provided with rollers 17 which are journaled in fixed bearings and ride on suitable tracks 18 on the under side of the platform 13. The latform 13 is provided with a stop 19 whic engages the end of the casing an limits the inward movement of the litter.

The lower art of the casing is provided 20, each provided with a heater 21 for heating the air entering the casing. A deflector 22. causes a distribution of the air and prevents direct drafts of une ual temperature from striking the body of t e atient. The

interior of the casing 4 is also ined with asbestos 23.

The operation ofv the device shown is as follows: The patient lies upon the latform 13 and is moved feet foremost into t e casing 4. The flexible hood is then drawn around the neck of the atient, and prevents the es- I ca e of air and eat at the opening 12.

he various uses of the device and other details of its operation are well known-and need not be herein more fully described.

The particular form of carriage having uprights riding on the floor is of great advantage since it avoids the necessity of having the tracks extended outward of the casing a distance equal to the length of the platform.

It will be seenthat some of the details of the construction shown may be altered without departing from the spirit of my invention.

What I claim as my invention and desire to secure by Letters Patent is a 1. In a device of the class described, the combination of a horizontally disposed 'casing, uprights at opposite sides of said casing, a plurality of cross bars extending transversely through the casing and connecting said uprights,

cross bars being formed of three parts having their adjacent ends fastened together by curing standards, chamber walls and rails means of bolts extending through said tracks, rigidly together. 10 substantially as described. 7 Signed at Chicago this 7th day of Decem- 2.
